Magnesium iodide is the name for the chemical compounds with the formulas MgI2 and its various hydrates MgI2(H2O)x. These salts are typical ionic halides, being highly soluble in water.




Magnesium iodide has few commercial uses, but can be used to prepare compounds for organic synthesis.




Magnesium iodide is actually steady from high temperature below the hydrogen environment, however decomposes within atmosphere from regular temps, switching dark brown in the discharge associated with much needed iodine. Whenever warmed within atmosphere, this decomposes totally in order to magnesium oxide.

An additional solution to put together MgI2 is actually combining powder much needed iodine as well as magnesium steel. To be able to acquire anhydrous MgI2, the actual response ought to be carried out inside a purely anhydrous environment; dry-diethyl ether may be used like a solvent.

Using magnesium iodide within the Baylis-Hillman response has a tendency to provide (Z)-vinyl substances.
